To all lwhom, 'i12/may concern:

a citizen of the'UnitedStates, residing at Detroit, inthe county of Wayne, State ofv have. invented a new anduseful'.. Improvement' in Window-Steadying Devices, of which the followingis a specicafA Michigan,

tion;

ria'ge window construction. In 'the better types of present day closedbodies forautomobiles some provision is made for keeping the window either completely closed or u partly open. A simplearrangeinent for this purpose is the familiar strap whichl can `be clamped to holdit in various positions. A

` more expensive and more desirable arrangement is the window lifting device such as roughly illustrated in Figure 1 and which is operated bya crank handle on the inside of the body-. I na -well built job 'the win dow is substantially rattle-proof 4in either 'thefdown or .the up 'position for the window` guide walls converge at top andvbottomand the header is made so asto fitit tightly 'in the closed position. Inniost-'of ithe iii-- termediate positions, however, the oo iniiion' rubber rollers or other devices that are now 1 quite generally used as antiLrattling devicesin a window of this kind do not jam the Window absolutely tightlagainst the side of the .groove for the reason. that they must be spaced for the farthest position thesash.

reaches inward in descending or rising. Consequently the window cannot be held absolutely tight from lateral vibration unmethods of construction.

der the present r Itis to provide afydevice to make the window absolutely rattle-proof when par;

tially raised that this invention is directed.

It performs the additional function, how.-

ever, ofinaln'ng the window rattle-tight case it has not been fitted in the way it should be when it is closed. These results and the structure to accomplish them willl fully appear in the moredetailed demore scription.

-andlowered position.' This is already part ofthe prior. art. 'The front wall gof the This invention-'relates t0 automobile car-'- top to sillconstitutes a jamb .againstwhich the felted-window sash h -is held when the sitioii lby the felted window is' in raised d Vthe fence. c.

It will be iioticedfthat the sash in passing l up by the roller j'varies as regards thediS- tance' from the inside 'of 'the' sash to the 'out- .side wall of the ,'way. l In `the construction shown this is due primarily to the inclination of theouter wall of the Way.v This inclination is almost a universal construction with windows vwhich lift overa fence. This v'variationofthe distance 'fromf'the inside J-ofthe sash to the .outsidewall of the window wayfwill occur in any window construction -in .which the Window sash is .at an angle with-respect to'the'outside Wall. of the Way. This occursA in the construction shown ink the drawings by reason of the outer .Wallof the window wavbeing inclined to the vertical.

- Obviouslytliere is considerable difference in' the distance from the inside ofthe' Sash to the outside wall of thef'wayat anyy given point. AConsequently the anti-rattler devices that'have heretofore beenemployed for this purpose have usually been placed at a posi. .tion calculatedto accommodate' the sash when in that position where the distance 4anti-rattler 'devices do 'practically Ano good when the window is partially raised for then "thev cease to function. I have designed an vanti-rattlercapable of accommodating itself. to the differential positions of the window. and yet not bear with suoli tenacity against thesash when the'maXiInuni pressure is eXl' erted as to .hamper the raising and lowering of the window.

The roller j, preferably made of bakelite or rubber, instead of being stationarv,

which are connected at their inner ends the bar n and which 'at their outer ends This housing Vfrom the inside 4of the sash to the outside wall of the way is maximum. Hence suchp can be screwed to the window frame'mold- -the widening of the distance from' the inside of the sash to the outside Wall of the Way as the window is raised past the roller. The roller having theoretically only a line contact with the window no matter how great the pressure upon the roller, and of course the roller revolving upon an axis, lessens the friction when th'e sash is raised or lowered. The anti-rattler, therefore, reduces to a minimum the hindrance to the raising and lowering of the sash While at the same time Ait is adapted to follow the sash regardless of its differential positions and insure a pressure against the sash which will hold it against the outside wall'of the way and prevent rattling.

What I claim is:

l. In a carriageconstruction, the combination of a pair of window-ways having their outer walls inclined from the vertical, a sash which in raising` or lowering is tipped against the outer walls of the Ways so that the distance between the inside of the sash and the outside wall of the way varies at any given point as the sash travels by such poijat, and a pressure device for keeping the sash against the outside Wall of the way, the

said pressuredevice'supported to the inside ing on the inside wall of the way being cutaway, a sash which when raising or lowering is tipped toward the outer wallof the ways so vthat the distance of the inside of the sash and the outside of the Ways varies as the sash travels by the cut-away portion 'of the said molding, and a pressure device for keeping the sash against the outside wall of the way regardless of the varying distance from the inside sash to the outside wall of the way, the said pressure device comprising an angle plate housing adapted to be fastened to the molding adjacentthe cut-away portion' and to cover said cut-away portion, guides supported by said angle plate housing, a saddle slidable on the guides, a roller journaled in the saddle and adapted to make contact with the inside of the sash, and spring means for normally keeping the roller projected outwardly through a slot in the angle` plate housing.

In Witness whereof, I have hereunto set my hand on the 24th day of January, `1918.
